New York CNN  —  A CDK Global system outage has affected nearly every aspect of the Mazda dealership in Seekonk, Massachusetts, where Ryan Callahan is general sales manager. He says it won’t be a simple fix. “The financial impact it will directly have on us will take months to correct, if not years,” Callahan said. Car buyers and dealers are grappling with the shutdown of the retail software provider, which has left nearly 15,000 car dealerships across North America struggling to provide services to customers and scrambling to find temporary analog solutions to operate. CDK says it’s working on restoring its systems and expects them to be back online in several days, but in the interim, customers and dealership employees remain beset by long wait times, delays – and missed chances to make or save money. Tom McParland, the owner of Automatic Consulting, a national car buying service, said the outage was impacting customers because they have fewer dealers to choose from. “It reduces their ability to get a deal,” he said. “It limits the customer’s leverage.” Some dealers also can’t apply factory rebates without CDK’s software, so customers may miss out on money-saving deals. For customers looking to buy a car, McParland suggested casting a wide net and shopping outside their local market to find the best price. ‘They aren’t really able to drive their cars’ Midway Automotive uses a CDK product to register cars with the Massachusetts Registry of Motor Vehicles. Owner Michael Deveney says that after the shutdown on Wednesday, the dealership started sending customers to their local RMV office in order to register their cars in person after purchase. “That was up until Thursday. Then customers started being told that (the RMV) wasn’t taking any walk-ins,” he said. “They were probably getting flooded with customers and started turning people away.” Deveney said one customer got increasingly agitated because he couldn’t register his car. “Getting an appointment might take three or four days, and in that time they aren’t really able to drive their cars,” he added. Some 30 miles north in Lynn, Katelyn Salvato says she hasn’t been able to register a vehicle since last Tuesday. Salvato works as a title clerk for Pride Motor Group, registering cars for three dealerships. “Today… I sent 21 registrations to be done manually at the Massachusetts RMV,” she said, adding that the RMV won’t accept transactions from dealership employees. “The transactions must be dropped off within the designated hours (of 10 am to 3 pm), and the runner can’t wait for them.” Callahan echoed those concerns. Under normal circumstances, the CDK software allows the dealership to register a vehicle almost instantaneously, but now the process faces heavy delays. “Our remote registration system is rendered useless without CDK to talk to it. We’ve had to send a runner with the registrations to the DMV to be competed in packs, costing several days where prior it took hours,” Callahan said in an interview with CNN. If a vehicle isn’t registered within seven days of purchase, the state penalizes both the dealership and customers. The Massachusetts Department of Transportation, which oversees the state’s RMV, has not responded to CNN’s request for comment. Service and sales go analog Salespeople and service employees who spoke with CNN say they’ve resorted to using pen and paper to process purchases, which has drawn out the amount of time it takes to buy a car, according to Scott Campbell, a salesman at Capital City Buick GMC in Berlin, Vermont. He estimates wait times have doubled or tripled. Nicolas, who declined to provide his full name because he was unsure about his employer’s stance on speaking to the media, is a clerk in the parts department of a Porsche dealership in Los Angeles. He said he has been using “a mix of pen and paper, Excel sheets, and extra care for each invoice” since the shutdown. Since many dealerships use CDK products to manage inventory, Nicolas said his department is now forced to manually record inventory parts, which slows their work down significantly. “We don’t have clear view of stock and have to do regular inventory on our most used parts,” he added. But sometimes the analog workarounds are not enough. Delays at dealerships Several buyers and repair customers tell CNN they’ve experienced long delays. Don Aycock told CNN he drove 90 miles round-trip from his home to a car dealership in Clay County, Florida, to buy a new Buick on Thursday, a day after the CDK shutdown. He told CNN he was able to buy the car but was unable to sign the title. “We got a call from them today that we can come next Thursday to sign the paperwork for the title and get a permanent license plate,” he said, noting that it will be another lengthy round-trip drive. In San Diego — where temperatures in recent days have been pushing 90 degrees — Robbie Jacob and his wife tried to make an appointment at a Kia service center to fix their car’s broken air conditioning unit. Jacob said the center told them it was unable to service the car, citing the CDK cyber incident, as there were no appointments available and all walk-ins were suspended until next week. Other software providers take note CDK Global isn’t the only management system used by dealerships, and the back-to-back cyber incidents affecting the company have put their competitors on high alert, as well. Cox Automotive, which operates the Dealertrack and VinSolutions software systems to manage documents and customer service, told CNN that it temporarily stopped integrating its systems with CDK after the outage “as a precautionary measure to prioritize safety and security for our clients.” “While actively supporting our customers to continue to run their business, we established a secure microsite that our customers are actively using now to access support and guidance, work-arounds and actions they can take while CDK systems are not available,” the company said. Tekion, another software company used by dealerships, said it has “seen an increase in inquiries from dealers in light of the recent CDK incident.” And other industry experts told CNN that switching from one system to another is not an action that dealerships can just take on a whim. Businesses are often locked into a multi-year contract with a software provider. Switching software also means training employees, making it a lengthy process.
